I want to know if I should perform an FDR before I update to Lollipop. I remember in years past, it was said to be recommended to Factory reset before updating android operating system to the latest and greatest. I guess it was to guarantee a clean slate for the update with no residual issues from any rogue apps or previous OS bugs. Is it still recommended and did most of the Turbo forum members here do it. I kinda hate to start over from scratch and don't want to lose any if my 360 watch faces, though I think I have that worked out. I just want a smooth experience. Any thoughts or recommendations?
